SPECIFICATION forming part of Letters Patent No. 292,774, datedjJanuary 29, 1884. Application filed September 14, 1883. (No model.)

To @ZZ whom it may concern:

Bc it known that I, RIcHARD Vosn, of the city of New York, county and State of New York, am the inventor of certainl Improvements in Spring Holders or Cups for Holding Interior Springs in Position, of which the following is a specification, reference being had to the drawings forming part thereof, in which Figure l is a sectional view of my improve- @ment in position, showing the interior and exterior springs.

Fig. 2 is aA plan or perspective plan view of my improvement.

Hitherto cups for holding interior springs have been made bybeing cast in a solid body,

so that if the interior spring should be of a` less dimension than the diameter of the cup the spring would drop through and be broken when the load was applied. If the'spiral were of a greater diameter than that of the cup at the top, when the load was placed on the top, the coil would be forced down into the cup, thus causing a fracture of the rim of the cup, and thus breaking the cup, and the spiral would drop through and .break the outer spring by getting into its coils. VIf not dropping through, the spring had to be removed,`

thus causing waste of time and of material. By means of my improvement I obviate this fracture by allowing an expansion of my cup at the very point where fracture generally occurs.

In the drawings, A is the cup, which is made of a greater diameter at the top thanl at the bottom, having in some cases, when desired, a conical shape, such as has been heretofore used by me; butthis cup need not be a cone-shaped cup, but contracted at the bottom sufficient to'keep the inner spring from dropping through and holding said spring ready for action.

B is the rim ruiming around the top, at about right angles to the side C, and is di- D2 D3 by means of cutting away the metal at points E E E" E. These cut-aways E, Snc., extend through the whole of rim B and down into the side or surface of part C to point d.

ThenV desired, the lower end or the bottom of part C may be scalloped or otherwise recessed, as shown in Fig. 2 at F F F, &c.

H is an interior coiled spring, and G is the exterior spring, and I is the cap over all, and on which the load is placed.

It will now be seen that if the inner coil, H, is placed in the cup A, and the cup placed in position in coil G, and the cup and spring H are held suspended therein by means of rim B, the top of the inner coil should pro-v ject above the plane of the rim B, and aheavy load placed on top of plate I should force the coil H down into the cup A, either the rim B would be broken, or the cup would be Vvcracked, or the coil would be broken, and,

falling down through into the bottom, would probably cause a` fracture of the inner coil by the pieces getting in among its spirals. N ow, if such is the fact in my case, that the inner coil is of greater dimensions than the diain eter of the cup, and the load is placed on the coil projecting above the rim of the cup, the parts or sections D D, Src., are further separated, the diameter of the cup at that end is made greater, so that the spring sinks down into the cup, out of the way of the load, obviating any great strain or pressure on the coil and 011 the cup, and thus saving both from fracture. 'Ihe inner coilis held tight,

however, in the cup, as this expansion only extends to part of the way of the side C.

By my improvement I also save metal; but if the inner coil is found to incline to one side more than it should, by driving the scallop or edge Fin against the coil, lateralmotion is prevented and the coil is heldin its proper bearing position. The bottom of the cup, by means of these scallops or projections, may be lessened orwidened by means of 'pounding as will be readily seen.

When a double interior coil is desired to be used, a cup at each end, each holding one spring, may be used.

What I cla-im, and desire to secure by Letters Patent, is u l u l. A cup for holding inner spiral springs, constructed with a rim divided into Vsections by means of cutting away part ofthe them in or widening vor pulling them 4 apart, y

metal in the rim and sides of said cup, sub- ViLness my hand this 30th day of August., stantially as shown, :uid for the purpose speoi- 1883.
